Abstract

Small pelagic fish stocks are the highest and most caught fish stocks for Indonesian consumption. Pelagic fish generally live in shallow water and form schools that act as intermediate consumers in the food chain (between producers and larger fish), thus requiring protective measures. This study aims to determine the growth rate and utilization of pelagic fish in Indramayu Regency, West Java. Fish sampling uses a literature review of data information from fishermen and other economic actors who utilize the pelagic fish ecosystem. Pepetek fish are expected to die earlier than tuna because pepetek fish reach asymptotic body length earlier than tuna with low growth factors in the results of studies with high growth rates. Pepetek, kurisi, kuniran, cob and tembang have very low exploitation rates below 50%. For mackerel, the recovery rate is 70.85%. This means that the average catch that occurs in Indramayu waters does not exceed the optimal limit of 50% so that there is no overfishing.

Abstract

The 3D seismic survey activities carried out in the Sangetoh Field, Kangean work area, Java Sea, East Java Province are part of exploration activities in an effort to find locations and potential oil and gas reserves in the sea. However, in practice it still has an impact on the surrounding area, especially the emergence of concerns that it will disrupt the activities of fishermen, shipping, and even disturb the existing marine biota. Efforts are being made by taking a persuasive approach to fishermen by conducting outreach, forming survey teams and complaint forums, coordinating with related parties, placing warning signs around the survey area, and ensuring that the location is free of marine biota. and waste. Impact monitoring is carried out by carrying out an inventory of documents and continuing to make direct observations of each 3D seismic survey carried out. In addition, tourism development also needs to be done by improving and developing tourism supporting facilities and infrastructure, as well as improving and leveling the planting of marine biota and vegetation in the region.
